Notas de aplicación
- Accurate Temperature Sensing with an External P-N Junction &mdash AN137PDF, 540 Kb, Archivo publicado: sept 20, 2012
Many Linear Technology devices use an external PNP transistor to sense temperature. Common examples are LTC3880, LTC3883 and LTC2974. Accurate temperature sensing depends on proper PNP selection, layout, and device configuration. This application note reviews the theory of temperature sensing and gives practical advice on implementation.Extracto del documento - Overview of the EEPROM in LTC PSM Devices &mdash AN145PDF, 3.0 Mb, Archivo publicado: mayo 10, 2014Extracto del documento
